Over the past decade, digital image capturing systems have effectively made SLR cameras, video cassette recorders (VCRs), and video printers obsolete. When trying to capture images directly to a computer, most practitioners face some limitations directly related to the outputs on the CCU and monitor and the inputs of the computer itself. Software compatibility may also be an issue. The ultimate image quality and user friendliness are critical factors [1–5, 13].

Newer sophisticated digital capture systems (Figure 3.11) offer 4K and FULL HD 3‐D image quality and easy export of data to the hospital network or patient files. Most units also have an internal storage of limited volume, including patient‐related information. Still images and videos are captured and stored on the unit's hard drive or alternatively recorded onto USB flash drives, CD‐ROM/DVD, or external devices.

Some endoscopic camera systems contain an integrated capture system (Figures 3.9b). These integrated systems lack some of the features of independent image capture and archiving systems [1–5]. However, they are useful for simple documentation when more sophisticated digital capture systems are not available.
